OREANDA-NEWS. December 26, 2012. Engineers on the Cadillac ATS took a chemistry-lab approach to deliver the brand's first entry into the compact luxury sedan segment.  Metals such as Martensitic alloys and ultra-high strength steel, among other materials, help make ATS one of the lightest vehicles in the class.

Still, the ATS is among the safest, earning a 5-star overall crash test rating in the New Car Assessment Program run by the National Highway Traffic Safety Administration.
